Coiled tubing
This study explores enhancing gas production through a novel combination of prestimulation using a coiled tubing unit and high-rate matrix acidizing.
This paper describes the use of coiled tubing in a pilot project for carbon dioxide injection, enabling evaluation of the conversion of an existing oil field for CCS purposes and derisking storage-development uncertainties before having to cease hydrocarbon production.
This paper describes a case history in the UAE in which the cleanout of scale contaminated with naturally occurring radioactive material was conducted successfully.

This study illustrates how a combination of a straddle-packer system and a downhole real-time telemetry successfully stimulated up to 38 stages while maintaining packer-seal integrity and downhole pressure. -
The authors of this paper describe an underbalanced coiled-tubing drilling campaign in the operator’s onshore fields using a closed-loop system design.
-
The authors describe a casing-leak-repair alternative to allow continued hydraulic fracturing of an unconventional formation.
-
The authors describe coiled tubing operations that used a riser on a monohulled vessel already performing riserless interventions.

The authors describe the applicability of 110,000-psi yield-strength quench-and-tempered coiled tubing strings in high-pressure sour environments through implementation of a custom-fit coiled tubing integrity and risk-mitigation program.
-
This paper describes a new concept for a reel mover used for coiled tubing deployment and operation.

In this year’s feature are two case histories and an equipment-development paper, all of which are, by accident rather than design, from operations undertaken in the Gulf States. Each, in its own way, exemplifies the engineering decisions and balances that must be weighed to provide the best solution within limiting parameters and the considerable effort this may take…

This paper illustrates a novel methodology that enabled the safe application of coiled tubing abrasive perforation to increase production in a sour horizontal extended-reach oil producer.

This paper’s authors describe the development of a coiled tubing (CT) nitrogen-lift design in which CT and geothermal reservoir simulations were combined to overcome modeling limitations.
